Theses are free-standing speakers without square brackets in perfect condition. BeoLab 4000 active speakers. Manufacturer: 1997 - present Designer: David Lewis Colours: Silver "When it comes to sound reproduction we believe that there is only one relevant parameter: how close can we get to the originally recorded sound. We believe in an obligation not to distort the artist's intentions by adding unnatural elements to the acoustic image. So all Bang & Olufsen speakers share the same purpose. They differ in size and shape and in terms of sound pressure level. But they are all designed to reproduce the natural, unaltered sound as closely as possible" -Bang & Olufsen catalog 2001-2002.
